The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses shell commands for project environment detection, including npx tsc --version, node -v, and a node -e one-liner to parse package.json dependencies. These are standard operations for identifying the development ecosystem.
[COMMAND_EXECUTION]: The diagnostic script scripts/ts_diagnostic.py utilizes subprocess.run with shell=True to execute diagnostic tools such as grep and tsc. This implementation is used to facilitate command piping and output redirection (e.g., grep ... | wc -l), which is appropriate for a local diagnostic utility.
[COMMAND_EXECUTION]: Validation steps in SKILL.md include running npm run typecheck, npx tsc --noEmit, and npx vitest, which are routine verification tasks in TypeScript development workflows.
[DATA_EXPOSURE]: The skill reads local project configuration files (tsconfig.json, package.json) and source code files (via grep) to provide context-aware expert advice and diagnostic reports.
